SHOCKEB ATTACHMENT FOR GRAIN-BINDEBS.

Specification of Letters Patent.

Patented July 6,1920.

Application filed December 20, 1918. Serial No. 287,580.

To all whom it may concern I Be it known that I, James A. MCELROY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Im rovementsin Shocker'Attachments for rrain-Binders; and I do declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. 1

This invention relates to a shocker attachment for grain binders and one of the objects thereof is to provide an inexpensive, durable and efficient attachment which may be readily connected to a known form of grain binder and so'correlated therewith as to efficiently form received sheaves into shocks and deposit the shocks upon the round with the heads of the grain upstandmg so that the shocks may subsequently be gathered for threshing.

With these and other objects in view, my

invention consists of the parts and combinations of parts to be referred to herein-. after and illustrated in the drawings, itv

being understood that changes in form, proportion and minor details of construction may be resorted towithout departing from the spirit of the invention or sacrificing any of its advantages.

In the drawings,

Fig. II is a view partly in section and partly in elevation of the shock forming arms.

Fig. III is a view at-right angles to the section shown in Fig. II. a

Fig. IV is an end view of the shock forming attachment.

' Fig. V is a.,detail perspective view of the sprocket and slip clutch, driven for the initial turning movement of the shock compressor member.

Fig. V1 is a detail view of a high speed clutch for the shock compressor member.

Fig. VII is a detail view of the clutch actuator.

Fig. VIII'is a perspectiveview showing the shock compressor member and the shock forming-arms, and Fig. IX is a side view of pressor' member.

Referring now to the drawings by numerals of reference in which corresponding the shock comreference numerals designate corresponding 7 parts throughout the several views:

1 designates a side frame ofa binder on 1 I whichis the usual drive shaft 2 provided with a sprocket 3 from which motion is communicated to the movable parts of the invention. 4 designates the shock former frame which is secured to the bar 1 by the bracket arms 5 and 6 connected to one side of the frame 4, the other side being secured to a frame 7 upon which the adjustable caster wheel 8 is mounted. This adjustment permits the raising and lowering of the frame 4 to compensate for varying heights of grain.

Inasmuch as there is considerable side draft present in binders due to the location of the cutter bars, it is obvious that by attaching the frame 4 rigidly to the side bar 1 of the binder the draft will be more equally distributed on each side of the same, In the drawings I have shown ashaft 9 mountedin bearingbrackets 10 and 11 on the frame 4 and this shaft carries a sprocket 12 around which a chain belt 13 travels, said chain being engaged by the teeth on thesprocket? whereby 'a' rotation of the shaft 2 willcause a corresponding rotation of the shaft 9. On the shaft 9 is also a beveled pinion 14 meshing with a beveled gear 15 on a transverse shaft 16 to which a suitable clutch 17 is attached.- One of the clutch members is adapted to be moved into and out of clutching engagement with the sprocket 18 on sald shaft 16, the particular.

construction of the clutch forming no part of my invention. The clutch is, however, capable of being moved into and out of clutching engagement by means of the clutch actuating arm 19 pivoted on the crank shaft 20 andconnected to the frame 4 by a spring 21. The rear end .22 of the clutch actuator, 19 may be connected to a cord 23 whereby the operator from the binder may move the actuator at will. the clutch 17 is actuated so that the sprocket 18 will be driven, motion will be imparted to the chain 24 which passes around a sprocket 25 adapted to drive the shaft 26 the pawl 29 on sprocket 25 in such a manner that the sprocket 25 may over-run the pawl when motion is imparted to the shaft 26 at a greater rotative speed than that of the sleeve 29' to which the pawl 27 is secured.

By reference to Figs. I to VII it will be observed that the shaft 26 to which the shock compressor, settling member and shock up-ender is attached, is loosely journaled in the sleeve 30 and that on the sleeve 30 is a beveled gear 31 adapted to-engage a corresponding gear 32 capable of being connected to the shaft 9 through the medium of a clutch 33. The clutch 33 is provided with an actuator 34 normally held inoperative by a spring 35. The clutch actuator, however, is adapted to be operated by means of a projection or finger 36 on the intermediate or main body'portion 37 of the shock former compressing and up-ending member, as will be presently explained. The compressor, shock former and up-ending member 37 has attached to it two hinged leaves 38 and 39 foldable in opposite directions as best indicated in Figs.- I and VIII, the leaf 38 being resiliently connected to the mem' ber 37 by the rod 39, one end of which is fastened at 40 and the other end of which passes through a bracket-41 and carries a spring 42. The other member 39 has a spring actuated link or rod 43 .for yieldingly connecting it to the member 37 and this member is also provided with bowed or outwardly curved shock positioning arms 44 and 45, (see Figs. I,VIII and IX).

In actual practice the actual up-endi'ng may be performed by the leaf or member 39; the member 37 serving. to settle and com-- press the shock. v

On one edge of the member 37 is a lug or projection 46 adapted to contact with a lug or projection 47 on the sleeve 30, the puriose of which will 'be apparent hereinafter.

he shaft 26 is provided with a crank arm 48 which carries a pitman 49 through which one end of the crank 50 also passes, said crank being on v a shaft 51 and passing through a. pitman 52 engaged by the crank 53 on shaft 20. Shaft 20 also carries acrank 54 at its opposite end to which a pitman 55 is attached, said itman engaging a crank 56 in the bearing 5 on the side of the frame 4, there being a rigid toothed gear 58 on said bearing 57 corresponding to a similar gear 59 rigid on the bearing 60 through which the shaft 51 passes. struction of the crank shafts 51 and 56 are best shown in Figs. II and III in which it will be observed that the crank shafts pass through the rlgrdgears 58 or 59, as the case may be, and rigidly engage the rods 61,

The shaft con-- which constitute thesupports and form part of the shock former, there being cradle arms or supports 62 on each of the arms 61 and these supports or arms are inwardly curved so that, in their normal position, they will form swings or cradles to receive the sheaves as they pass from the conveyer-63, having previously been deposited there from the deck 64 of the binder.

Depending from the side bars of the frame 4 are brackets 65 and 66 in which is journaled a curved rocker shaft 67 carrying inwardly projecting teeth or fingers 68 directed toward the shock former and this shaft 67 carries a crank 69 connected to the pitman 55 so that when the shock forming arms are actuated the shaft 67 and fingers will also be operated.

Since none of the shock former mechanism can operate without operation of the svith the difference that instead of the sheaves being deposited from the deck to a fork. they will pass onto the conveyer 63 to be eposited in the shock forming slings. \Vhen a suflicient number'of sheaves has been received the operator will pull upon the cord 23 to clutch the sprocket 18 to the shaft 16, at the same time the latch 70 will be moved: out of the path of the swinging crank 48. Since the sprocket 18 will be driven by the shaft 16, motion will becommunicatcd to the sprocket 25 on the shaft 26, this being effective in initially rotating the shock compressing member which will be swung until it is passed through an arc of about 90; then the arm 36 will come into contact with the actuator 34 to throwthe gear 32 into clutching engagement with the shaft 9. j Since the gear 15, sprocket 18 and s rocket 25 constitute a reduction gearing,= t e shaft 26 will be initially driven 'at a speed considerably. less than that of the shaft 9; therefore, the shock compressing member will be initially swung in-an are at a relatively slow speed. When it has described an arc of about 90, however, and thrown the clutch 33 into engagement with the gear 32 so that the shaft 26 may be driven through the gear 31, the remainder of speed and completed at a. relatively high speed. As the shock compressor is moving through its are however, the-crank 48 will be moving thrdiigh its arc and the shafts 51, 20, 56 and 69 will also be swinging so that the rods 61 will be moving in a vertical are because they are fast to the shafts 51 and 56 and since their gears 58 and 59 fast on the shaft 61- will roll on the fixed gears 58 and 59, the fingers or slingarm 62 will not only move in a vertical are but will also slide apart. The shaft 67 is also swinging with the teeth directed downwardly so that the I shock can be released from the embracing arms 44 and 45 with the shock up-standing.

-The crank 48 is on the end of the shaft 26, and carries the pitman 49 having an elon- K gated slot in one end which engages a crank .50 on the shaft 51 lVhen crank 48 is first released by latch 70, the pitma n will let the fingers 62 drop to release the shock but as the shaft 26 continues to rotate at a more rapid rate to complete its revolution, the pitman 49 will draw the crank 50 down and, through the pitman 52, effect a similar movement to the crank 53 to, through 59 and 61, swing the fingers 62 back to shock-receiving position.

From the foregoing description it will be observed that when the clutch 17 is tripped the shock butts drop to the ground, the

shock settler andcompressor 37 revolves top forward one quarter turn at which position it is in a horizontal plane over the shock, settling the shock solid on the ground; then fast clutch 33 comes into play, making full revolution of the shock settler and compressor 37 thereby compressing the shock and releasing it at substantially one operation and automatically returning to its origi nal position, ready for another shock.

When the clutch 17 is tripped, the shock formers, consisting of the rods 61 and fingers 62, rotate, thus forming the shock, closing in the front and opening in the rear to let shockthrough when the fast clutch 33 is in operation, thereby compressing and releasing the shock and then rotate back to theirori inal positions.

Whiled hai e shown only one form of my. invention, it is obvious that it may partake of other forms while involving the same generic principle, the particular construction shown for the purpose of illustration being capable of shocking nine to fifteen bundles with the shock untied although a tying attachment may be utilized, if desired,

In actual practice the shocks may'be ut in shock rows. convenient for a shock loaer.

By practising my invention,-the loose grain ordinarily lost along the bundle rows goes into the shocks and is thereby saved.

During the operation of the mechanism heretofore described, the leaves 38 and 39 will gather in the respective sides of the approved manner.

. Having thus described my invention what I claim as new therein, and desire to secure by Letters-Patent, is:
